Spontaneous Reboots (I thought it was Virtualbox Kernel Modules)

Unless you're using ECC RAM, bad RAM should still be #1 on your
watchlist, closely followed by bad PSU. Even RAM that worked fine in
the past can start exhibiting bit errors a few years later (maybe due
to mechanical stress, i.e. vibrations or frequent temperature
differences?) and esp. el cheapo PSUs have the tendency to degrade
over time.

Of course, a software bug may always be possible. Have you tried to
get a core dump? If so, does the error always happen at the same place
(backtrace / bt is your friend)? If the error keeps occurring at
different locations, it's almost always dodgy hardware.
